I figure a 800 volt architecture that pumps out 800 horsepower will need 747 amps
Spread across 7 batteries in parallel (107 amps) and powering a large performance truck. . . The battery will get hot and the amperage is high. . . The fuses will be tested .
But I am just spitballing here and don't know for sure
For context the Model 3 fuses can only handle about 1/3 that current.
